Description
Technical Field
[0001] This utility model relates to the field of screening equipment technology, and in particular to a screening device for abrasives in chemical processing of materials. Background Technology
[0002] Most natural abrasives have unstable properties and have been gradually replaced by synthetic abrasives. In industrial production, materials chemical abrasives are used for processing. Abrasives are sharp and hard materials that can be used to grind softer material surfaces. Therefore, abrasives are essential materials in the manufacture of precision products. The higher the content and purity of the main components of materials chemical abrasives within the specified quality index range, the better the performance of the abrasive. Therefore, it is necessary to use screening equipment to screen materials chemical abrasives and ensure the uniformity and consistency of the abrasives.
[0003] Existing abrasive screening equipment for materials and chemicals typically involves feeding the abrasive material into the uppermost screening chamber through a feed pipe, then starting a vibrator. The vibrator, in conjunction with springs, drives multiple screening chambers and their internal screens to vibrate at a high frequency. This causes abrasive particles of different sizes to fall into the screening chambers for screening under the action of vibration, and then be discharged through the discharge pipes corresponding to the screening chambers, thus achieving multi-stage screening of the abrasive material.
[0004] However, due to the high distance between the discharge pipe and the collection bucket below, the abrasive may collide with the surface of the collection bucket or scatter outside the collection bucket as it falls into the collection bucket, causing some abrasive to fail to fall into the collection bucket for storage and affecting the collection efficiency of the abrasive. Utility Model Content
[0005] The technical problem this invention aims to solve is that, due to the high distance between the discharge pipe and the collection bucket below, the abrasive material may collide with the surface of the collection bucket or scatter outside the collection bucket during the process of falling into the collection bucket through the discharge pipe, resulting in some abrasive material failing to fall into the collection bucket for storage and affecting the collection of abrasive material.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a material chemical processing abrasive screening device, including a machine body, a plurality of springs are arranged on one side of the machine body, a vibrator is arranged on one side of the machine body, the output end of the vibrator is connected to the lowest screening chamber, a plurality of screening chambers are arranged on one side of the machine body, a discharge pipe is arranged on one side of each of the plurality of screening chambers, a feed pipe is arranged on one side of the uppermost screening chamber, a dustproof device is arranged on the side of the uppermost screening chamber near the feed pipe, and an extension device is arranged on one side of each of the plurality of discharge pipes.
[0007] The effect achieved by the above components is as follows: First, the chemical abrasive material is fed into the uppermost screening chamber through the feed pipe. Then, the vibrator is started, which, together with multiple springs, drives multiple screening chambers and their internal screens to vibrate at a high frequency. Under the action of vibration, abrasive particles of different specifications fall into the multiple screening chambers for screening. Subsequently, they are discharged through the discharge pipe corresponding to the screening chamber, thus achieving multi-stage screening of the abrasive.
[0008] Preferably, the extension device includes a first ring, which is fixedly sleeved on the surface of the discharge pipe. A screw hole block is fixedly connected to one side of the first ring, and a screw rod is threadedly connected to the inner wall of the screw hole block. One end of the screw rod is rotatably connected to a second ring through a bearing. An intercepting cloth is fixedly connected to the side of the second ring close to the first ring, and the other end of the intercepting cloth is fixedly connected to the first ring.
[0009] The effect achieved by the above-mentioned components is as follows: By setting up the extension device, the first ring is first sleeved and fixed on the discharge pipe, so that the second ring and the intercepting cloth wrap around the outlet of the discharge pipe. At this time, the screw is manually rotated, so that the screw moves up and down along the inside of the screw hole block, so that the screw drives the second ring to move up and down through the bearing, so that the second ring pulls the intercepting cloth to move, so that the intercepting cloth gradually extends. When the second ring moves to the position where it is completely inside the lower collection cylinder, the second ring, together with the intercepting cloth, extends the length of the discharge pipe outlet, reduces the height difference between the discharge pipe and the lower collection cylinder, and allows the abrasive to directly enter the collection cylinder through the intercepting cloth and the second ring. This achieves the extension treatment of the discharge pipe outlet position, reduces the situation where the abrasive collides with the surface of the collection cylinder or scatters outside the collection cylinder during the process of falling due to the high distance between the discharge pipe and the lower collection cylinder, resulting in some abrasive failing to fall into the collection cylinder for storage, thus improving the collection efficiency of abrasive.
[0010] Preferably, a screw block is fixedly connected to the end of the screw away from the second ring, and the surface of the screw block is provided with multiple anti-slip protrusions.
[0011] The effect achieved by the above-mentioned components is that by setting the screw block, the contact area between the hand and the screw can be increased, allowing the operator to easily rotate the screw by manually turning the screw block.
[0012] Preferably, the surface of the intercepting cloth is provided with a plurality of elastic ropes, which are arranged at equal intervals.
[0013] The effect achieved by the above components is as follows: by setting the elastic rope, the elastic rope can provide elasticity to the intercepting cloth, allowing it to retract autonomously, which facilitates the quick storage and repositioning of the intercepting cloth. At the same time, the elastic rope is taut while the intercepting cloth is extending, which can provide a certain limiting effect for the intercepting cloth.
[0014] Preferably, a guide rod is fixedly connected to one side of the second ring, and a circular hole block is fixedly connected to one side of the first ring, with the surface of the guide rod slidably connected to the inner wall of the circular hole block.
[0015] The effect achieved by the above components is that by setting a guide rod, the guide rod can be located inside the circular hole block to assist in limiting the second ring, thereby reducing the shaking of the second ring when it is driven by the screw.
[0016] Preferably, the inner wall of the second ring is fixedly connected with a plurality of rubber strips, and the plurality of rubber strips are arranged at equal intervals.
[0017] The effect achieved by the above components is that by setting multiple rubber strips, the multiple rubber strips can assist in intercepting the falling abrasive, reducing the impact force of the abrasive on the inner wall of the collection bucket when it falls.
[0018] Preferably, the dustproof device includes an L-shaped rod with a rectangular groove on one side and two circular holes on the same side. A pin is slidably connected to the inner wall of one of the circular holes. A circular hole plate is slidably connected to the inner wall of the rectangular groove. The size and shape of the pin are adapted to the size and shape of the inner wall of the circular hole plate. A protective plate is fixedly connected to one side of the circular hole plate, and the surface of the protective plate is larger than the inner wall of the feed pipe.
[0019] The effect achieved by the above components is as follows: By setting up a dustproof device, the protective plate is first manually moved, causing it to move left and right along the inside of the rectangular groove. When the protective plate moves to a position that completely covers the feed pipe outlet, the inner wall of the circular plate coincides with the inner wall of the circular hole. At this time, the pin is manually moved to a position that inserts into the circular hole and the circular plate, fixing the circular plate and the protective plate in place. This ensures that the protective plate completely covers the feed pipe inlet and intercepts external dust and impurities, achieving dustproof protection for the feed pipe. This reduces the possibility of external dust and impurities falling into the screening chamber through the feed pipe when the machine is idle, causing dust and impurities to mix into the subsequently fed abrasive, resulting in dirty abrasive and affecting the quality of abrasive processing.
[0020] Preferably, a handle is fixedly connected to one side of the protective plate, and the inner side of the handle is provided with multiple anti-slip protrusions.
[0021] The effect achieved by the above components is that by setting handles, the handles can provide a point of leverage for personnel, allowing personnel to easily move the protective plate by manually moving the handles.
[0022] The beneficial effects of this utility model are:
[0023] By setting an extension device, the outlet position of the discharge pipe can be extended and adjusted, which reduces the situation where the abrasive material collides with the surface of the collection bucket or scatters outside the collection bucket during the process of falling due to the high distance between the discharge pipe and the collection bucket below. This results in some abrasive material failing to fall into the collection bucket for storage, thus improving the collection efficiency of abrasive material. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Figure 1-4The device for screening abrasives in chemical processing of materials, as shown, includes a body 1. Multiple springs 2 are arranged on one side of the body 1, and a vibrator 3 is also arranged on one side of the body 1. The output end of the vibrator 3 is connected to the lowest screening chamber 4. Multiple screening chambers 4 are arranged on one side of the body 1, and each screening chamber 4 has a discharge pipe 5 on one side. A feed pipe 6 is arranged on one side of the highest screening chamber 4, and a dustproof device 8 is arranged on the side of the highest screening chamber 4 near the feed pipe 6. Extension devices 7 are arranged on one side of each of the discharge pipes 5. First, chemical abrasives are fed into the highest screening chamber 4 through the feed pipe 6. Then, the vibrator 3 is started, causing the vibrator 3, in conjunction with the multiple springs 2, to drive the multiple screening chambers 4 and their internal screens to vibrate at a high frequency. This causes abrasive particles of different specifications to fall into the multiple screening chambers 4 for screening under the action of vibration, and then be discharged through the discharge pipes 5 corresponding to the screening chambers 4, achieving multi-stage screening of the abrasives.
[0033] Figure 2 and Figure 3 The extension device 7 shown includes a first ring 71, which is fixedly sleeved on the surface of the discharge pipe 5. A screw hole block 72 is fixedly connected to one side of the first ring 71, and a screw 73 is threadedly connected to the inner wall of the screw hole block 72. One end of the screw 73 is rotatably connected to a second ring 75 via a bearing. An intercepting cloth 76 is fixedly connected to the side of the second ring 75 near the first ring 71, and the other end of the intercepting cloth 76 is fixedly connected to the first ring 71. By setting up the extension device 7, the first ring 71 is first sleeved and fixed on the discharge pipe 5, so that the second ring 75 and the intercepting cloth 76 cover the outlet of the discharge pipe 5. At this time, the screw 73 is manually rotated, so that the screw 73 moves up and down along the inside of the screw hole block 72, so that the screw 73 drives the second ring through the bearing. The second ring 75 moves up and down, causing it to pull the intercepting cloth 76 to move, gradually extending the intercepting cloth 76. When the second ring 75 moves to a position where it is fully inside the lower collecting cylinder, it extends the outlet length of the discharge pipe 5 in conjunction with the intercepting cloth 76, reducing the height difference between the discharge pipe 5 and the lower collecting cylinder. This allows the abrasive to directly enter the collecting cylinder through the intercepting cloth 76 and the second ring 75, achieving an extension of the outlet position of the discharge pipe 5. This reduces the likelihood of the abrasive colliding with the surface of the collecting cylinder or scattering outside the collecting cylinder during its descent due to the high distance between the discharge pipe 5 and the lower collecting cylinder, thus preventing some abrasive from successfully falling into the collecting cylinder for storage and improving the collection efficiency of the abrasive.
[0034] Figure 2 and Figure 3The screw 73 shown is fixedly connected to a screw block 74 at the end away from the second ring 75. The surface of the screw block 74 is provided with multiple anti-slip protrusions. By setting the screw block 74, the contact area between the hand and the screw 73 can be increased, allowing the personnel to easily rotate the screw 73 by manually rotating the screw block 74. The surface of the intercepting cloth 76 is provided with multiple elastic ropes 77, which are arranged at equal intervals. By setting the elastic ropes 77, the elastic ropes 77 can provide elasticity to the intercepting cloth 76, allowing it to retract autonomously, facilitating the quick storage and repositioning of the intercepting cloth 76. At the same time, the elastic ropes 77 are taut when the intercepting cloth 76 extends, which can provide a certain limiting effect for the intercepting cloth 76.
[0035] Figure 2 and Figure 3 A guide rod 78 is fixedly connected to one side of the second ring 75, and a circular hole block 79 is fixedly connected to one side of the first ring 71. The surface of the guide rod 78 is slidably connected to the inner wall of the circular hole block 79. By setting the guide rod 78, the guide rod 78 can be located inside the circular hole block 79 to assist in limiting the second ring 75, reducing the shaking of the second ring 75 when it is driven by the screw 73. Multiple rubber strips 710 are fixedly connected to the inner wall of the second ring 75. The multiple rubber strips 710 are arranged at equal intervals. By setting multiple rubber strips 710, the multiple rubber strips 710 can assist in intercepting the falling abrasive, reducing the impact force of the abrasive on the inner wall of the collection bucket when it falls.
[0036] Figure 4 The dustproof device 8 shown includes an L-shaped rod 81. A rectangular groove 82 is formed on one side of the L-shaped rod 81, and two circular holes 83 are formed on one side of the L-shaped rod 81. A pin 84 is slidably connected to the inner wall of one of the circular holes 83. A circular perforated plate 85 is slidably connected to the inner wall of the rectangular groove 82. The size and shape of the pin 84 are adapted to the size and shape of the inner wall of the circular perforated plate 85. A protective plate 86 is fixedly connected to one side of the circular perforated plate 85. The surface of the protective plate 86 is larger than the inner wall of the feed pipe 6. By setting up the dustproof device 8, the protective plate 86 is first manually moved, so that the protective plate 86 drives the circular perforated plate 85 to move left and right along the inside of the rectangular groove 82. When the protective plate 86... When the plate 6 is moved to a position that completely covers the outlet of the feed pipe 6, the inner wall of the circular perforated plate 85 coincides with the inner wall of the circular hole 83. At this time, the pin 84 is manually moved to a position where it is inserted into the circular hole 83 and the circular perforated plate 85 to fix the position of the circular perforated plate 85 and the protective plate 86. This allows the protective plate 86 to completely cover the inlet of the feed pipe 6 and intercept external dust and impurities, thus achieving dust protection for the feed pipe 6. This reduces the possibility of external dust and impurities falling into the screening chamber 4 through the feed pipe 6 when the machine body 1 is idle, causing dust and impurities to mix into the subsequently fed abrasive, resulting in dirty abrasive and affecting the quality of abrasive processing.
[0037] Figure 4 A handle 87 is fixedly connected to one side of the protective plate 86 shown. The inner side of the handle 87 is provided with multiple anti-slip protrusions. By setting the handle 87, the handle 87 can provide a point of leverage for personnel, so that personnel can move the protective plate 86 conveniently by manually moving the handle 87.
[0038] Working principle: First, the chemical abrasive material is fed into the uppermost screening chamber 4 through the feed pipe 6. Then, the vibrator 3 is started, which, together with multiple springs 2, drives multiple screening chambers 4 and their internal screens to vibrate at a high frequency. Under the action of vibration, abrasive particles of different specifications fall into the multiple screening chambers 4 for screening. Then, they are discharged through the discharge pipe 5 corresponding to the screening chamber 4 and fall into the collection bucket below for storage, thus achieving multi-stage screening of the abrasive.
[0039] First, the first ring 71 is fitted and fixed onto the discharge pipe 5, so that the second ring 75 and the intercepting cloth 76 cover the outlet of the discharge pipe 5. At this time, the screw 73 is manually rotated, so that the screw 73 moves up and down along the inside of the screw hole block 72. The screw 73 drives the second ring 75 to move up and down through the bearing, so that the second ring 75 pulls the intercepting cloth 76 to move, so that the intercepting cloth 76 gradually extends. When the second ring 75 moves to the position where it is completely inside the lower collection cylinder, the second ring 75, together with the intercepting cloth 76, extends the length of the discharge port of the discharge pipe 5, reduces the height difference between the discharge pipe 5 and the lower collection cylinder, and allows the abrasive to directly enter the inside of the collection cylinder through the intercepting cloth 76 and the second ring 75, thus achieving the extension treatment of the outlet position of the discharge pipe 5.
[0040] First, manually move the protective plate 86 so that it drives the perforated plate 85 to move left and right along the inside of the rectangular groove 82. When the protective plate 86 moves to a position that completely covers the outlet of the feed pipe 6, the inner wall of the perforated plate 85 coincides with the inner wall of the circular hole 83. At this time, manually move the pin 84 so that the pin 84 moves to a position that inserts into the circular hole 83 and the perforated plate 85 to fix the position of the perforated plate 85 and the protective plate 86. This allows the protective plate 86 to completely cover the inlet of the feed pipe 6 and intercept external dust and impurities, thus achieving dust protection for the feed pipe 6.
[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
